Nation states and large companies or individuals with significant stake in BTC running mining softwar thing seems obviously how it will inevitably end up. I don't really care what big blockers thing this isn't a "new thing" they've been running their mouths about this for a decade and every time they do something it ends up just being a way to push a scam where they control it and make money. Check the bcash/btc pair.

Profit driven mining companies are honestly kind of not a very good force and push for lots of weird scams to encourage mining like memecoins on BTC or "dog pictures", and also regularly mine just pump and dump alts (including the biggest BTC miners).

Mining should just be as distributed as possible and integrated into stranded power likely generating a small if any profit.
